摘　　要：矿体赋存于中二叠统中上部凝灰岩中。17号饼状铁异常面积大,峰值最高。V1矿体南、北控制545米。V2矿体南西、北东走向控制370米。次级构造发育,厚度大、品位富,为低硫、低磷炼铁用褐铁矿矿石。The ore body is in the tuff of Middle P mid - upper formation. The area of Fe anomaly 17 is large, disc - like, with the highest peak value. The NS controlled length of ore body V1 is 545m, the SW - NE strike controlled length of ore body V2 370m. the secondary structure is developed. It is the low S, P limonite ore, utilizable for iron -making, thick and grade rich in Fe.
